1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Introduction: Dual-task training is proposed as a rehabilitative strategy to mitigate motor and cognitive impairments in patients with Parkinson's disease (PD). This systematic review and meta-analysis sought to consolidate existing information regarding the impact of dual-task therapies on health-related quality of life (HRQoL) and cognitive performance in middle-aged and older persons diagnosed with PD. Methods: A systematic review of randomized controlled trials (RCTs) published to May 2026 was performed utilizing PubMed, EBSCOhost, Scopus, and Web of Science. The chosen studies adhered to the PICOS framework. The Methodological quality and certainty of evidence were assessed using the Cochrane Risk of Bias 2 tool and GRADE framework, respectively. The review protocol is recorded in PROSPERO under the number CRD420251159680. Results: Out of 3,037 identified records, 10 RCTs met the eligibility criteria and were included in the systematic review, of which 9 contributed data to the meta-analysis. The meta-analysis showed a statistically significant but modest effect on HRQoL measured with the Parkinson's Disease Questionnaire-39 (SMD = 0.35; 95% CI: 0.03-0.67; Conclusion: Dual-task interventions may produce a modest improvement in HRQoL in people with Parkinson's disease, whereas the current evidence does not demonstrate significant benefits for the cognitive outcomes assessed. These findings should be interpreted cautiously given the limited number of studies, methodological limitations, and clinical heterogeneity across interventions.
